In\nparticular, a carbon sequestration potential productivity\ncalculation method based on the potential mean annual increment\nis proposed. This package is applicable to both natural forests\nand plantations. It can quantitatively assess stand’s potential\nproductivity, realized productivity, and possible improvement\nunder certain site, and can be used in many aspects such as\nsite quality assessment, tree species suitability evaluation,\nand forest degradation evaluation.
